Fluid & Gas Flow Equipment

Control Valve conserves air in diaphragm pump operation.

Utilizing microprocessor control air dispensing system, MizAir(TM) produces pulsating effect that allows for reduction of air consumption up to 50% without any loss of fluid flow during operation of Air Operated Diaphragm Pumps. Product consists of high-flow, NO, 2-way, Â-¾ in. NPT full flow valve and electronic control unit in NEMA4 enclosure. Intelligent device continuously monitors pump...

Fluid & Gas Flow Equipment

Manifold accommodates 4 regulators.

Up to 4 Model QB3 electronic pressure regulators can be mounted to manifold, which offers common supply and exhaust port with individual controlled outlet ports to minimize plumbing. Model QB3 is capable of controlling pressure or vacuum electronically by accepting command signal of either 0-10 V or 4-20 mA. Pneumatic output is linear to command input.

Pressure Regulator utilizes closed-loop technology.
Controls & Controllers

Pressure Regulator utilizes closed-loop technology.

Housed in IP65 enclosure, Series QPV provides high resolution pressure control. Output pressure is proportional to electrical command signal input and is unaffected by changes in supply pressure. Pressure is controlled by 2 solenoid valves; inlet valve operates proportionally to flow required to maintain system pressure. Variable orifice effect allows precise control of pressure at low flow...

Electronic Pressure Regulator uses O-rings for seat.
Controls & Controllers

Electronic Pressure Regulator uses O-rings for seat.

Model QB3 incorporates electronic pressure sensor that detects downstream pressure at work port for accurate regulation. Replaceable O-rings for intake and exhaust valve are set into groove that captures O-ring, but leaves room to move slightly and seal correctly for positive shut-off. Regulator accepts 0-10 V or 4-20 mA command signal and provides analog output that corresponds to actual...

Electronic Pressure Regulator delivers high relief flow.
Controls & Controllers

Electronic Pressure Regulator delivers high relief flow.

Offering reverse flow rates in excess of 25 scfm @ 100 psi, the QB3 electronic pressure regulator makes backpressure and high relief applications possible without use of a quick exhaust valve. It uses solid-state pressure sensor to monitor pressure at work port and electronically adjusts the integral regulator to desired pressure by filling or exhausting air from system. Product can be calibrated...
